I've just arrived in Sydney and was hoping to find some friendly backpackers that would be up for meeting for a drink/exploring.
I'm 18 and from the UK and have 5 weeks to travel the east coast so if anyone's doing anything similar it would be cool to meet up!
Good luck meeting people. A good hostel for meeting people is the Flying Fox in Katoomba, the blue mountains, which I am sure will be one of your early stops.
Most people either travel Sydney - Melbourne or reverse so hopefully you'll meet people to do a section of the trip.
